If one opens file.R and does =C-RET= on a line, it sends it to the current ESS R process running (or starts a new process and then sends the line).
Is this possible from babel blocks? I would find this extremely helpful when troubleshooting in order to run lines of code up to my problem spot vs. my current practice of copying, switching buffers, then yanking into the R session buffer. Is this already possible? I looked around at some of the completions for =M-x org-babel-*=, but didn't see anything promising. Thanks, John
